This 15020-1 manual folder features a D2 tool steel blade with an ambidextrous thumb hole and a plain cutting edge. The layered green and black G10 handle features a rib cage pattern for great grip. The Bone Collector line has the AXIS lock system which makes the knife easier and faster to open and close. The pocket clip can be reversed for right or left-handed tip-up carry. Overall this is an excellent knife with a good feel and weight.
